Researchers from Queen's University Belfast in the UK measured the way that 'Oumuamua', reflects sunlight, and found it similar to icy objects covered with a dry crust.

Four Earth-sized planets have been discovered orbiting the nearest Sun-like star, which is about 12 light years away and visible to the naked eye, scientists said. Two of the planets are super-Earths located in the habitable zone of the star, tau Ceti.

cientists have found evidence of a giant ringed gas planet which may be up to fifty times more massive than Jupiter, orbitting a star over thousand light years away from Earth. They predict that these eclipses are caused by the orbit of the yet undiscovered giant planet.
